Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Jun. 4, 2015 in the Korean Intellectual Property Office and assigned Serial number 10-2015-0079188, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an electronic device. More particularly, the present disclosure relates to an electronic device including a touch screen and a method of controlling the electronic device.

BACKGROUND

Recently, various electronic devices used in a practical life are being modernized. In particular, following a rapid growth of a smart phone market, after some or all functions of a smart phone are added to various electronic devices used in a practical life, the various electronic devices are released.

Specifically, a smart phone may receive a touch input of a user through a touch screen. When a touch input of a user approaches the touch screen within a predetermined distance (e.g., 5 mm), the smart phone may detect a position over the touch screen, which corresponds to the touch input of the user.

In addition, the smart phone is operated to detect a proximity of an object using a proximity sensor.

In most electronic devices, an infrared ray (IR) sensor using infrared light is used as the proximity sensor.

In order to smoothly emit infrared light from a light source and receive reflected infrared light, the IR proximity sensor includes an IR filter, through which only infrared light is passed, on a transparent window glass of the smart phone.

As an example of a method of sensing a proximity of an object using the IR sensor, when infrared light emitted through a hole of an emitting unit is received through a hole of a sensing unit, the proximity of the object may be determined using information on a time when the emitted infrared light is received.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

As described above, an object proximity sensing technique using the infrared ray (IR) sensor may be used.

However, in order to include the IR proximity sensor, two holes having independent spaces are necessary to prevent interference of an emitting unit (e.g., an emitter) and a sensing unit (e.g., a detector). At this time, the two holes may limit a design of a front portion of an electronic device in manufacturing the electronic device.

In addition, when the proximity of the object is to be sensed using a touch screen rather than the IR sensor, the proximity of the object, which is far outside a sensing distance of the touch screen, may not be sensed, or a gesture according to a movement of the object may not be recognized.

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a method of sensing a proximity using a proximity sensor and a touch screen.

In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a touch screen, a proximity sensor overlapping a portion of the touch screen to form an overlap area of the touch screen, and a processor configured to sense a proximity of an object located over the touch screen using the proximity sensor, change a proximity sensitivity of the overlap area of the touch screen, and sense a position of the object using the changed proximity sensitivity of the touch screen.

In accordance with another aspect of the present disclosure, an electronic device is provided. The electronic device includes a housing including a first surface and a second surface opposite to the first surface, a display exposed through the first surface, a touch panel that is disposed between the display and the second surface, the touch panel including a first electrode and a second electrode, wherein the touch panel calculates plane coordinates of a user input to the display based on a change of a capacitance formed between the first electrode and the second electrode, and a capacitive sensor including a third electrode and a fourth electrode, the capacitive sensor measuring a proximity between an external object and the first surface of the housing based on a change of a capacitance formed between the third electrode and the fourth electrode.

In accordance with another aspect of the present disclosure, a capacitive proximity sensor rather than an IR sensor is used, therefore a hole may not be included on a front window of a smart phone. Thus, a limit of a design may be reduced.

In accordance with another aspect of the present disclosure, a simple proximity recognition of an object using a capacitive proximity sensor is broke away, a proximity sensing performance of a touch screen is enhanced using a proximity sensor and a touch screen, and a position of an object may be more minutely measured.

Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses various embodiments of the present disclosure.

DETAILED DESCRIPTION

The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there is not an element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

The electronic device 101 may include a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, and a communication interface 170. In some embodiments, the electronic device 101 may omit at least one of the above components or further include other components.

The bus 110 may include a circuit for connecting the components 110 to 170 and transmitting communication (for example, control messages and/or data) between the components.

The processor 120 may include one or more of a CPU, an AP, and a communication processor (CP). For example, the processor 120 may carry out operations or data processing related to control and/or communication of at least one other element of the electronic device 101.

The memory 130 may include a volatile memory and/or a non-volatile memory. The memory 130 may store, for example, commands or data related to one or more other components of the electronic device 101. According to an embodiment, the memory 130 may store software and/or a program 140. The program 140 may include a kernel 141, middleware 143, an application programming interface (API) 145, and/or an application program (or “application”) 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an operating system (OS).

In the present specification, the application may be referred to as an app or an application.

The kernel 141 may control or manage system resources (for example, the bus 110, the processor 120, or the memory 130) used for executing an operation or function implemented by other programs (for example, the middleware 143, the API 145, or the application 147). In addition, the kernel 141 may access individual components of the electronic device 101 in the middleware 143, the API 145 or the application program 147, and thus may provide an interface capable of controlling or managing the system resources.

The middleware 143 may serve as, for example, an intermediary for allowing the API 145 or the application program 147 to communicate with the kernel 141 to exchange data.

Further, the middleware 143 may process one or more task requests received from the application program 147 according to priorities thereof. For example the middleware 143 may assign a priority of a use of the system resources (e.g., the bus 110, the processor 120, the memory 130, or the like) of the electronic device 101 to at least one program among the application program 147. For example, the middleware 143 may perform scheduling or load balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned to the one or more task requests.

For example, the API 145 may be an interface for enabling the application 147 to control a function provided from the kernel 141 or the middleware 143. In some embodiments, the API 145 may include at least one interface or a function (e.g., a command) for a file control, a window control, an image process, or a text control.

For example, the input/output interface 150 may serve as an interface that may transfer instructions or data input from a user or another external device to other component(s) of the electronic device 101. Further, the input/output interface 150 may output commands or data received from other component(s) of the electronic device 101 to the user or another external device.

In one or more embodiments, the display 160 may include a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 160 may display various types of contents (for example, text, images, videos, icons, or symbols) for users. The display 160 may include a touch screen, and may receive, for example, a touch, gesture, proximity, or hovering input by using an electronic pen or a part of the user's body.

In various embodiments of the present disclosure, the display 160 may be used as having a meaning identical to a touch screen.

For example, the communication interface 170 may set communication between the electronic device 101 and an external device (e.g., a first external electronic device 102, a second external electronic device 104, or a server 106). In some embodiments, the communication interface 170 may be connected to a network 162 through wireless or wired communication to communicate with one or more external devices (e.g., the second external electronic device 104 and/or the server 106).

The wireless communication may use at least one of, for example, long term evolution (LTE), LTE-advanced (LTE-A), code division multiple access (CDMA), wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), and global system for mobile communications (GSM) as a cellular communication protocol. In addition, for example, the wireless communication may include a short-range communication 164. The short-range communication 164 may include at least one of, for example, Wi-Fi, Bluetooth (BT), near field communication (NFC), and global navigation satellite system (GNSS). The GNSS may include at least one of, for example, a GPS, a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter, referred to as “Beidou”), and Galileo (European global satellite-based navigation system). Hereinafter, in the present specification, the “GPS” may be interchangeably used with the “GNSS”. The wired communication may include at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), recommended standard 232 (RS-232), and a plain old telephone service (POTS). The network 162 may include at least one of communication networks such as a computer network (for example, a local area network (LAN) or a wide area network (WAN)), the Internet, and a telephone network.

Each of the first and second external electronic devices 102 and 104 may be a device which is the same as or different from the electronic device 101. According to an embodiment, the server 106 may include a group of one or more servers. According to various embodiments, all or some of the operations performed by the electronic device 101 may be performed by another electronic device or a plurality of electronic devices (for example, the electronic device 102 or 104, or server 106). According to an embodiment, when the electronic device 101 should perform some functions or services automatically or by request, the electronic device 101 may make a request to another device (for example, the electronic device 102 or 104, or the server 106) to perform at least a portion of the functions or services instead of performing the functions or services by itself. The other electronic device (for example, the electronic device 102 or 104, or the server 106) may carry out the requested functions or the additional functions and provide results thereof to the electronic device 101. The electronic device 101 may provide requested functions or services based on the received results or after additionally processing the received results. To this end, for example, cloud computing, distributed computing, or client-server computing technology may be used.

FIG. 4 is a flowchart illustrating a method of sensing an object according to various embodiments of the present disclosure.

Referring to FIG. 4, an electronic device according to various embodiments of the present disclosure obtains initial coordinate information and capacitance information of an area (or overlap area) corresponding to a proximity sensor area in an area of a touch screen at operation S401.

More specifically, the electronic device may store coordinate information (or initial coordinate information) for the overlap area within the touch screen. In another embodiment, the electronic device may store information on the overlap area beforehand

In addition, the electronic device according to various embodiments may include a capacitive touch screen and a capacitive proximity sensor, and may obtain and store initial capacitance information of the capacitive touch screen and the capacitive proximity sensor before an object approaches. Additionally, when information on the overlap area is stored beforehand as described above, the initial capacitance information may be also stored beforehand

According to various embodiments, when the initial coordinate information and the initial capacitance information are obtained, the electronic device senses a proximity of the object over the touch screen using the proximity sensor at operation S403. The proximity sensor may detect the object within a first distance from the electronic device. A driving current of a first size may be applied to the proximity sensor, and a capacitance sensing field, for example, an electric field, may be formed based on the applied driving current. Here, the first distance in which the proximity sensor may detect the object may be comparatively longer than of a second distance in which the touch screen may detect the object. A current of a size lower than the first size may be applied to each touch sensor of the touch screen, and thus a size of a capacitance sensing field formed by the touch screen may be smaller than a capacitance sensing field formed by the proximity sensor.

According to various embodiments, the proximity sensor may be disposed under the touch screen or at an edge of the touch screen, and may form the capacitance sensing field where a change of a capacitance may be sensed. The proximity sensor may form the capacitance sensing field on the touch screen. But, the above descriptions are simply examples, and a position of the proximity sensor is not limited. When the object approaches an area within a proximity sensor sensing distance from the proximity area (e.g., among an upper area of the touch screen), the electronic device may sense the change of the capacitance according to a change of the capacitance sensing field formed by the proximity sensor. When the change of the capacitance is sensed, the electronic device may determine that the object approaches the area of the touch screen correspondingly to the change of the capacitance (e.g., the upper area). Meanwhile, when the object is disposed in an area equal to or longer than the second distance and shorter than the first distance, the proximity sensor may detect the object and the touch screen may not detect the object.

According to various embodiments, when the proximity of the object is sensed, the electronic device changes a proximity sensing sensitivity by the touch screen at operation S405.

More specifically, the electronic device may change a sensitivity of the touch screen and may sense a position of the approached object using the touch screen. More specifically, the electronic device may increase a distance from the touch screen at which a position of the object can be sensed. In an embodiment, the electronic device may increase a size of the driving current applied to each touch sensor of the touch screen. According to the increase of the driving current, a size of an electric field formed by a touch sensor may be increased, and thus a distance at which the touch screen can sense an object may also be increased.

According to various embodiments, when the proximity sense sensitivity of the touch screen is changed, the electronic device senses a movement of the object through the touch screen at operation S407. As described above, according to the increase of the distance at which the touch screen can sense the object, the touch screen may additionally detect the position and the movement of the object while detecting the object.

More specifically, the electronic device according to various embodiments may obtain position information of the approached object using the touch screen of which the sense-able distance is increased to the position of the object. More specifically, the electronic device may sense the change of the capacitance according to the change of the capacitance field formed by the touch screen, and may sense at least one of the position of the object or the movement of the object correspondingly to the change of the capacitance.

According to various embodiments, the position information of the approached object may include the coordinate information obtained by the electronic device using the touch screen, and coordinates may be a horizontal coordinate obtained using the touch screen.

When the position information of the object is obtained, the electronic device may obtain the change of the position of the approached object, may sense the movement of the approached object based on the change of the obtained position, and may recognize a gesture corresponding to the movement of the sensed object.

In addition, the FPCB panel 502 may include a proximity sensor 504 disposed at a lower portion 503 of the touch screen or at an edge illustrated in FIG. 5B of the touch screen.

The proximity sensor may be a plate type. The proximity sensor of the plate type may be formed of copper. In the proximity sensor having the plate type and including copper, the larger an area of the plate, the larger a critical value of a capacitance which may be sensed by the proximity sensor and the longer a sense distance for maintaining the same capacitance.

Referring to FIG. 6A, the touch screen may include a plurality of touch sensors 610a, 610b, 610c, 610d, 620a, 620b, 620c and 620d (i.e., indium tin oxide (ITO) layers) of a lattice type.

The plurality of touch sensors may include a plurality of conductive line sensors 610a, 610b, 610c and 610d and a plurality of sense line sensors 620a, 620b, 620c and 620d. The electronic device may apply a predetermined value of current through the plurality of conductive line sensors 610a, 610b, 610c and 610d, and may form a capacitance sense field in a sense-able area in an area over the touch screen through the plurality of sense line sensors 620a, 620b, 620c and 620d based on the applied current. The electronic device according to various embodiments of the present disclosure may sense a change of a capacitance by an approach of an object to the sense-able area using the touch screen, and may obtain position information on an x,y coordinates plane for the approached object based on the sensed change of the capacitance.

Meanwhile, according to various embodiments, the proximity sensor may overlap at least a portion of the touch screen corresponding to touch sensors 610a, 610b, 610c, 610d, 620a, 620b, 620c and/or 620d. The electronic device may store the initial coordinate information for some of the overlap area of the touch screen overlapping the proximity sensor on the x,y coordinates plane in a memory (not shown) beforehand The electronic device may change a proximity sensitivity of the overlap area of the touch screen based on the initial coordinate information stored beforehand when the object approaches the electronic device. More specifically, the electronic device may increase a size of a current applied to the plurality of conductive line sensors 610a, 610b, 610c and 610d. According to the increase of the size of the current applied to the plurality of conductive line sensors 610a, 610b, 610c and 610d, a size of the capacitance sense field and the sense-able distance may also be increased. Therefore, the electronic device may detect an object disposed at a comparatively far distance based on a signal from the touch screen, and may detect at least one of the position and the movement of the object.

FIG. 6B is a cross-sectional view of a touch screen and a proximity sensor according to various embodiments of the present disclosure.

Referring to FIG. 6B, an electronic device according to various embodiments may include a sensor 631, a touch screen having touch sensors 641a, 641b, 641c, 641d and 643 and proximity sensors 642a, 642b, 642c and 644.

The touch screen may include a plurality of touch sensors 641a, 641b, 641c, 641d and 643 of a laminated plate type. The proximity sensor may also include a plurality of proximity sensors 642a, 642b, 642c and 644 of a laminated plate type.

Each of the plurality of touch sensors 641a, 641b, 641c, 641d and 643 and each of the proximity sensors 642a, 642b, 642c and 644 may be a conductor forming a capacitor.

According to various embodiments, first touch sensors 641a, 641b, 641c and 641d, a second touch sensor 643, first proximity sensors 642a, 642b and 642c and a second proximity sensor 644 may be electrically connected with each other in series. Since each of the sensors is connected with each other in series, capacitors formed by each of the sensors may be connected in series. Therefore, a sum of capacitances of the plurality of sensors having the plate type is in reverse proportion to the number of the sensors, and thus the sum of capacitances of the plurality of sensors having the plate type is lower than a capacitance of each sensor. Accordingly, the sense-able distance from the touch screen to the object, which may be sensed through the plurality of sensors is increased in proportion to the number of the sensors.

According to various embodiments, each of the plurality of sensors may be electrically connected to a processor (not shown) of the electronic device. The processor may sense the change of the capacitance through each sensor, and may sense the proximity of the object and the position of the approached object using the sensed the change of the capacitance.

According to various embodiments, each sensor may be arranged as a plurality of plates type in order to reduce a parasitic capacitance by each sensor 631, 641, 642, 643 and 644 to a value lower than a predetermined value such that the processor may normally sense the capacitance change. In an embodiment, a structure for shielding may be further disposed between the plurality of plates, and thus the parasitic capacitance may be reduced. The parasitic capacitance due to the sensors 631, 641, 642, 643 and 644 is inversely proportional to an area A of the plate of each sensor.

According to various embodiments, the plurality of touch sensors 641a, 641b, 641c, 641d and 643 may be connected to a first electrode and a second electrode (not shown). The first electrode or the second electrode may include ITO or a silver nano wire (i.e., A_g nano wire). The processor may apply the current to the plurality of touch sensors 641a, 641b, 641c, 641d and 643 through the first electrode and the second electrode.

According to various embodiments, the plurality of proximity sensors 642a, 642b, 642c and 644 may be connected to a third electrode and a fourth electrode (not shown) having a resistance lower than that of the first electrode and the second electrode. According to various embodiments, the third electrode or the fourth electrode may include copper. According to various embodiments, the third electrode or the fourth electrode may be disposed on an FPCB in which a touch panel is included. According to various embodiments, the third electrode or the fourth electrode may be formed on a shield layer (not shown) for shielding an electric field (e.g., an electric field formed by a capacitance) related to a display.

The position of the proximity sensor may be changed in the electronic device according to an embodiment.

Each proximity sensor may have an area equal to or larger than an area corresponding to a critical value of a capacitance value which may be sensed by the processor.

FIG. 7 is a cross-sectional view illustrating a touch screen and a proximity sensor obtaining information on an overlap area according to various embodiments of the present disclosure.

Referring to FIG. 7, according to various embodiments, an electronic device may obtain information on a first initial capacitance C_EV1 sensed in an upper area of the touch screen, among the first initial capacitance C_EV1 and a second initial capacitance C_EV2 increased by a plurality of proximity sensors 730a, 730b, 730c and 740 before an object approaches the electronic device, and may store the obtained information on the first initial capacitance C_EV1 in a memory (not shown).

In addition, the electronic device may define an area where the first initial capacitance C_EV1 is sensed in an area of the touch screen as an initial increase area (or an overlap area), may obtain coordinate information for a corresponding initial increase area (or the overlap area) from the touch screen, and may store the coordinate information in the memory. Here, the initial increase area may mean an area where a capacitance is increased by the proximity sensor, and may be referred to as the overlap area.

FIG. 8 is flowchart illustrating a method of obtaining information on an overlap area according to various embodiments of the present disclosure.

Referring to FIG. 8, according to various embodiments, a processor of an electronic device determines whether there is coordinate information on a proximity sensor area (i.e., the overlap area) overlapping the proximity sensor area in an area of a touch screen in the electronic device at operation S801.

When it is determined that there is no coordinate information on the overlap area, the processor determines whether an object approached an upper area of the electronic device (i.e., the touch screen) is sensed at operation S803.

When the approached object is sensed, the processor determines a sense of the approached object until the approached object moves far away from the electronic device and thus a proximity of the object is not sensed.

When it is determined that the approached object is not sensed, the processor determines whether a change of a capacitance is sensed by a proximity sensor using the touch screen at operation S805.

As a result of the determination, when the change of the capacitance by the proximity sensor is sensed through the touch screen at operation S807, the processor stores coordinate information on an area on the touch screen where the change of the capacitance is sensed in a memory at operation S809.

The current capacitance C₂₁ may be larger than the initial capacitance. An electronic device may determine a position of the object or movement information of the object based on a signal from a touch screen area in which the current capacitance C₂₁ is increased.
